Zgjidhja

  1. 23×34=24=12\dfrac{2}{\cancel{3}} \times \dfrac{\cancel{3}}{4} = \dfrac{2}{4} = \dfrac{1}{2}
  2. 59×3=53\dfrac{5}{\cancel{9}} \times \cancel{3} = \dfrac{5}{3}
  3. 52×58=2516\dfrac{5}{2} \times \dfrac{5}{8} = \dfrac{25}{16} == 19161\dfrac{9}{16}
  4. 89×35=815\dfrac{8}{\cancel{9}} \times \dfrac{\cancel{3}}{5} = \dfrac{8}{15}
  5. 72:94=72×49=149\dfrac{7}{2} : \dfrac{9}{4} = \dfrac{7}{\cancel{2}} \times \dfrac{\cancel{4}}{9} = \dfrac{14}{9} == 1591\dfrac{5}{9}
  6. 265×114=28620=14310\dfrac{26}{5} \times \dfrac{11}{4} = \dfrac{286}{20} = \dfrac{143}{10}
